WRINGER.

'Application filed November According to my "invention the wrin'gerwhich comprises "a set of rolls and a hinge -over, is provided withaspring for exertm pi-essure on the rolls, and means for maintaining thespring in, :or for instan taneously releasing it irom, pressureentertingirelation :withfthe rolls.

In the preferred embodiment of *the in vention the cover isfconstruc tedinterio'rly with supporting members above and parallel with the journalsof the rolls and a flat spring is placed within the cover and its end'sar'e loosely mounted on the supporting members. Pressure blocks areseated onthe journals of the uppermost rollfand eXtend above thesupporting m'cmbers to'beengaged by the spring. rotatably adjustable camor dis'o is mounted in the coverandrengages the spring for varying thepressure exerted by it on therolls, and a cranlcor the'like effects therotatable adjustment of the cam "or disc. 7 j

The com is exteriorly provided with lockingmembers which may take theform of lateral projections; and a reciprocatingly movable lockingbarisslidably connected to the wringer frame and is provided wvithlocking memberswhich may take the form.

For an understanding of the invention -1eterenc-e is to be-had to thefollowing description and to the accompanying drawings, in Which: I sFig. 1 is a plan View of a 'Wring'er-constructed according to thisinvention,

parts throughoutthe specification and drawings. a s v Journalled in themain frame '25 are two wringer rolls 31 31 and bearing on the our- .nalsof the roll 31 are pressure, ,orfijojurnal, blocks 32. Hinged to the topof ithemain frame 25 is the cover 33 "provided with a downturnedflange'34, and-extending through the flange 34% ;are twosupportingmembers '35, the axles of which are parallel with the journalsof the roll 31.

Centrally journa'-led in the 'topofthecover is the axle 37 of a rotatable cam 'or Le'ccentrically anounteddisc 38, and {fitted on the end of the" axle r-beyond'the {cover 33, isa :crank '39.

and r by '1 the weight I :Other 'types of springs andtension devices lmay be employed in lieu of the specific type shown and described and itnot intended that the invention should be limited to this specificconstruction. I

The cover, including the pressure exerting means, are for convenience,termed the cover part, and for holding the cover part in operativerelation with the wringer rolls, a

closed position and maintain the spring in pressure exerting relationwith the rolls. The'hooks on the locking bar are comparatively long andso shaped that they draw the hinged cover down to its locked positionand impose the pressure of the spring on the pressure blocks 32.

At the bottom of each hook 43 is a slight recess into which theprojections 44 drop when the locking bar is moved to the limit of itslocking position, for preventing the inadvertent displacement of thehooks from the projections 44. Extending horizontally from the lockingbar is a lug 45 formed with a slot 46 through which is entered a wringerrelease lever 47, the lower end of which is fulcrumed at 48 to the mainframe 25. The actuation of the lever 47, operating through the slot 46,effects the movement of the locking bar in one direction for theengagement 7 of the hooks 43 with the projections 44 and in the oppositedirection for the release of the hooks from them. The release of thelocking bar from the projections immediately releases the cover part andrelieves the pressure of the spring on the blocks 32 and wringer roll31, the ends of the spring then resting on. the supporting members 35.

Having thus fully described my in run tion what I claim as new a nddesire to secure by I Letters Patent is:

l. A wringor comprising a wringer frame, a set of rolls therein, ahinged cover for the rolls, a spring within the cover for exertingpressure on the rolls, a rotatable eccentric disc engaging the springfor varying the pressure exerted by it on the rolls, and areciprocatingly movable locking bar having a shdable connection with thewringer frame for securing the cover and maintaining the spring inpressure exerting relation with the roll s. '2. A. Wringer comprising awringer frame, a set of rolls thereln, a hinged cover for the rolls, aspring within the cover for exerting pressure on the rolls, a rotatableeccentric disc engaging the spring for varying the pressure exerted byit on the rolls, and a reciprocatingly movable locking bar having aslidabl-e connection with the wringer frame for securing the cover andmaintaining the spring in pressure exerting relation with the rolls, thecover having projections and the locking bar having hook-shaped membersfor engaging the projections.
